Tauri

A Tauri plugin that lets AI agents (Claude Code, Cursor, etc.) interact with your Tauri app through screenshots, DOM inspection, and input simulation using the Model Context Protocol (MCP).

Features

• Screenshots — capture the app window on macOS, Linux, and Windows
• DOM access — read the full HTML of any webview window
• Element interaction — click, type, drag, hover via simulated input
• JavaScript execution — run arbitrary JS in the webview context
• Element position — find elements by id, class, tag, or text content

Installation

# Cargo.toml
[dependencies]
tauri-plugin-mcp = { git = "https://github.com/DonsWayo/tauri-mcp", optional = true }

Register the plugin in your Tauri app:

// src-tauri/src/lib.rs
#[cfg(feature = "mcp-e2e")]
app.plugin(tauri_plugin_mcp::init())?;

The plugin opens a Unix domain socket at /tmp/<app-name>-mcp.sock that MCP clients connect to.

macOS Screenshots

The plugin uses screencapture -l <CGWindowID> instead of xcap. This means:

• No Screen Recording permission required for the Tauri app itself
• Only Terminal (or your terminal emulator) needs Screen Recording access
• Works with unsigned debug builds without code signing entitlements
• Avoids a crash in xcap::Window::all() triggered by certain system windows on recent macOS versions

Linux Screenshots

Uses xcap for X11 window capture with multi-pass window matching by app name and title.

Usage with Claude Code

Add to .mcp.json:

{
  "mcpServers": {
    "nucel-e2e": {
      "type": "stdio",
      "command": "node",
      "args": ["path/to/mcp-server/build/index.js", "/tmp/your-app-mcp.sock"]
    }
  }
}
